Convert between Inch water (4°C) and other Pressure units.

Inch Water (4°C) as a Unit of Pressure

Inch water (4°C), often abbreviated as inH2O, is a non-standard unit of pressure measurement. It is based on the height of a column of water at a temperature of 4 degrees Celsius, which is the temperature at which water reaches its maximum density. This unit is commonly used in various industries, particularly in HVAC (Heating, Ventilation, and Air Conditioning) and fluid dynamics, to gauge low-pressure differentials.

One inch of water corresponds to approximately 249 pascals or 0.00403 psi. Despite being less widely used than standard units like pascals or psi, inch water provides a practical way to measure low pressure, as many systems operate within this range. Therefore, understanding inch water is beneficial for engineers and technicians dealing with pressure systems in buildings, air handling, and other fluid-related scenarios.
